README

Tony Format

Tony package houses the reference implementation of the Tony Format and several related tools.

O

o is a tool for managing objects stored in formats like Tony, YAML, and JSON.

Overview
# view files 
o view [ -color ] file [-e path=value ]
o v [ -color ] [-e path=value ] < file

# process a file with embedded transformation instructions
o eval file [-e path=value ] [ files... ]
o e [-e path=value ] < file

# path querys
o list '$...a[*]' [ files... ]
o l '$...a[*]' [ files... ]
o get '$.a[1]' [ files... ]
o g '$.a[1]' [ files... ]

# compute a diff between -- understands tags and strings and arrays!
o diff file1 file2

# match secrets and config maps
kustomize build . | o -y match -s '{ kind: !or [ ConfigMap, Secret] }' -
helm template . | o -y match -s '{ kind: !or [ ConfigMap, Secret] }' -

# patch a file -- understands tags and strings and arrays and diffs,
# all in merge patch style!
o patch -p patch [ file ]

# build manifests and helm charts with matches and patches and embedded transformations
o build [ manifest-build/] [ -l ]  [ -p profile ] [ -e path=value ] [-- path1=value1 path2=value2 ... ]
o b [ manifest-build/] [ -l ]  [ -p profile ] [ -s ] [ -e path=value ]

Functions

func Diff 

func Diff(from, to *ir.Node) *ir.Node

Diff produces a succint comparison of from and to. If there are no differences, Diff returns nil.

A resulting diff may be reversed using libdiff.Reverse.

A resulting diff may be used as a patch in Patch.

The structure returned by Diff contains a minimal set of changes indicated by yaml tags which double as patch operations.

  • if the types of from and to differ then the result is a node !replace from: from to: to

  • for ObjectType any field f in to but not in from has a field `f: !delete[(<orig-tag>)] ...`

  • for ObjectType any field f in from but not in to has a field `f: !insert[(<orig-tag>)] ...`

  • for any field f shared by from and to which is equal, it is absent in the result.

  • for any field f with a difference, it contains a diff of the value of f in from and respectively to.

For ArrayType nodes which differ, if both nodes are tagged by the same key with !key(<key>), they are treated as objects but presented as an array with tag !key(<key>).

For StringTypes, a string diff may computed and if the size of the string diff is less than half the size of the the smallest string

If only the tags differ, the tags !addtag(<tag>) !rmtag(<tag>) and !retag(<from>,<to>) will be present decorating a null.

func Match 

func Match(doc, match *ir.Node) (bool, error)

func Patch 

func Patch(doc, patch *ir.Node) (*ir.Node, error)

func Trim 

func Trim(match, doc *ir.Node) *ir.Node

Trim filters a document to only include fields/values that are present in the match criteria. It recursively processes objects and arrays, removing fields that aren't in the match. The result preserves the tag from the original document.
